DETAILED DESCRIPTION

Referring to the drawings, wherein like reference numbers indicate the same or corresponding elements throughout the views, FIGS. 1-8 illustrate an apparatus 10 for aligning sections of pipe according to one embodiment. Apparatus 10 can be used to align two adjacent sections of pipe, and to securely hold the two sections of pipe, to facilitate welding, or otherwise joining, the sections of pipe together to form a single, continuous pipe. For example, FIG. 1 illustrates apparatus 10 in surrounding relationship with a first section of pipe 12, and an adjacent, second section of pipe 14, to facilitate welding pipe sections 12 and 14, or to facilitate joining pipe sections 12 and 14 using a different process.

Referring to FIG. 4, apparatus 10 can include a first clamp member 16 and a second clamp member 18, which can be coupled with the first clamp member 16. In one embodiment, the first clamp member 16 can be hingedly coupled with the second clamp member 18 with a pair of hinges 20 (FIG. 8). Each one of the first clamp member 16 and the second clamp member 18 can be pivotable between an open position, for example, as shown in FIG. 2, and a closed position (FIGS. 1, 4 and 7). The first clamp member 16 and the second clamp member 18 can be opened sufficiently to receive first and second sections of pipe. Each one of the first clamp member 16 and the second clamp member 18, as well as other components of the apparatus 10, can be constructed from stainless steel, or any other durable and strong metal alloy or metal. Each of the hinges 20 can be constructed from a plurality of plates 21, for example, two or more plates 21 (FIGS. 2 and 8). Alternatively, each hinge 20 can be constructed from a single member, for example, a single plate.

The first clamp member 16 can include a first clamp jaw 22 and a second clamp jaw 24 longitudinally spaced from the first clamp jaw 22. The second clamp member 18 can include a first clamp jaw 26 and a second clamp jaw 28 longitudinally spaced from the first clamp jaw 26. Each one of the first clamp jaw 22 of the first clamp member 16 and the first clamp jaw 26 of the second clamp member 28 can be pivotally coupled with a first one of the hinges 20, and each one of the second clamp jaw 24 of the first clamp member 16 and the second clamp jaw 28 of the second clamp member 18 can be pivotally coupled with a second one of the hinges 20.

Each one of the first clamp jaw 22 of the first clamp member 16, and the first clamp jaw 26 of the second clamp member 18, can be configured to surround and engage respective portions of a first section of pipe, for example, respective portions of the first section of pipe 12, as shown in FIG. 1, when each one of the first clamp member 16 and the second clamp member 18 is in the respective closed position. Each one of the second clamp jaw 24 of the first clamp member 16, and the second clamp jaw 28 of the second clamp member 18, can be configured to surround and engage respective portions of a second section of pipe, for example, respective portions of the second section of pipe 14, as shown in FIG. 1, when each of the first clamp member 16 and the second clamp member 18 is in the respective closed position. The first clamp member 16 can be secured to the second clamp member 18 when each is in the respective closed position. In one embodiment, the first clamp member 16 can be clamped to the second clamp member 18 when each is in the respective closed position.

The apparatus 10 can also include a plurality of turnbuckle assemblies 30. As shown in FIGS. 10 and 11, each turnbuckle assembly 30 can include a rod 32 and a torquing member 34 secured to the rod 32, for example, by welding the torquing member 34 to the rod 32. In one embodiment, the torquing member 34 can be a nut, which can have a polygonal shape, as shown in FIGS. 10-12. In other embodiments, torquing members having other shapes and configurations, for example, torquing members having an elongated shape, can be secured to a rod of a turnbuckle assembly. The rod 32 of the turnbuckle assembly 30 can include a first portion 36 (FIG. 12) having right-hand male threads and a second portion 38 (FIG. 12) having left-hand male threads. The turnbuckle assembly 30 can also include a first clevis 40 and a second clevis 42 (FIGS. 10-11), with each being threadedly engaged with the rod 32. For example, each of the first clevis 40 and the second clevis 42 can define female threads, which permit the first clevis 40 to be threaded onto one of the first portion 36 and the second portion 38 of the rod 32, and which permit the second clevis 42 to be threaded onto the other one of the first portion 36 and the second portion 38 of the rod 32. The torquing member 34 can be positioned between the first clevis 40 and the second clevis 42.

Each one of a first of plurality of the turnbuckle assemblies 30, designated 30 a in FIGS. 1-5, 7 and 8, can be coupled with each one of the first clamp jaw 22 and the second clamp jaw 24 of the first clamp member 16, and can be adjustable, to vary the longitudinal spacing between the first clamp jaw 22 and the second clamp jaw 24 of the first clamp member 16. Each one of a second plurality of the turnbuckle assemblies, designated 30 b in FIGS. 1-8, can be coupled with each one of the first clamp jaw 26 and the second clamp jaw 28 of the second clamp member 18, and can be adjustable to vary the longitudinal spacing between the first clamp jaw 26 and the second clamp jaw 28. The first plurality of turnbuckle assemblies 30 a can be circumferentially spaced along the first clamp member 16, and the second plurality of turnbuckle assemblies 30 b can be circumferentially spaced along the second clamp member 18.

Each of the turnbuckle assemblies 30 can be adjusted by rotating the respective torquing member 34 and rod 32. As a result of the first portion 36 of the rod 32 having right-hand male threads and the second portion 38 of the rod 32 having left-hand male threads, rotation of the torquing member 34 and rod 32 in one direction can cause the first clevis 40 and the second clevis 42 to move toward each other, and rotation of the torquing member 34 and the rod 32 in the opposite direction can cause the first clevis 40 and the second clevis 42 to move away from each other.

In one embodiment, the first clevis 40 and the second clevis 42 can have different colors, which can facilitate the assembly and use of the turnbuckle assemblies 30. In one embodiment, one of the first clevis 40 and the second clevis 42 can have a silver color, as a result of zinc plating, and the other one of the first clevis 40 and the second clevis 42 can be plated to have a gold color. However, in other embodiments, any one of a variety of other color combinations can be used. In yet another embodiment, the first clevis 40 and the second clevis 42 can have the same color.

It can be desirable to have the first clamp jaw 22 and the second clamp jaw 24 of the first clamp member 16 move toward each other, and to have the first clamp jaw 26 and the second clamp jaw 28 of the second clamp member 18 move toward each other, when the torquing member 34 and the rod 32 of each one of the first plurality of turnbuckle assemblies 30 a, and each one of the torquing member 34 and the rod 32 of the second plurality of turnbuckle assemblies 30 b, respectively, is rotated in a first direction. Further, it can be desirable to have the first clamp jaw 22 and the second clamp jaw 24 move away from each other, and to have the first clamp jaw 26 and the second clamp jaw 28 move away from each other, when the torquing member 34 and the rod 32 of each one of the first plurality of turnbuckle assemblies 30 a, and each one of the second plurality of turnbuckle assemblies 30 b, respectively, is rotated in a second, opposite direction. This can be achieved by: coupling the first clevis 40 of each one of the first plurality of turnbuckle assemblies 30 a to the first clamp jaw 22 of the first clamp member 16; coupling the second clevis 42 of each one of the first plurality of turnbuckle assemblies 30 a to the second clamp jaw 24 of the first clamp member 16; coupling the first clevis 40 of each one of the second plurality of turnbuckle assemblies 30 b to the first clamp jaw 26 of the second clamp member 18; and coupling the second clevis 42 of each one of the second plurality of turnbuckle assemblies 30 b to the second clamp jaw 28 of the second clamp member 18. This arrangement can be facilitated by the color coding of the first clevis 40 and the second clevis 42.

Alternatively, the advantageous use of a color convention for the first clevis 40 and the second clevis 42 can be achieved by: coupling the second clevis 42 of each one of the first plurality of turnbuckle assemblies 30 a to the first clamp jaw 22 of the first clamp member 16; coupling the first clevis 40 of each one of the first plurality of turnbuckle assemblies 30 a to the second clamp jaw 24 of the first clamp member 16; coupling the second clevis 42 of each one of the second plurality of turnbuckle assemblies 30 b to the first clamp jaw 26 of the second clamp member 18; and coupling the first clevis 40 of each one of the second plurality of turnbuckle assemblies 30 b to the second clamp jaw 28 of the second clamp member 18.

In one embodiment, the apparatus 10 can include two of the first plurality of turnbuckle assemblies 30 a and two of the turnbuckle assemblies 30 b, as shown in FIGS. 3-5. Alternatively, one or both of the first plurality of turnbuckle assemblies 30 a and the second plurality of turnbuckle assemblies 30 b can include a single turnbuckle assembly 30, or more than two of the turnbuckle assemblies 30.

The apparatus 10 can include a plurality of circumferentially spaced spacers 44 (FIGS. 1, 2, 4 and 6), with each being attached to one of the first clamp member 16 and the second clamp member 18. Each of the spacers 44 can be cylindrical and can define a hollow interior that can be configured to receive a fastener. In other embodiments, spacers having other shapes can be attached to the first clamp member 16 and the second clamp member 18. Each one of the first clamp jaw 22 and the second clamp jaw 24 of the first clamp member 16, and each one of the first clamp jaw 26 and the second clamp jaw 28 of the second clamp member 18, can include a first frame 46 a and a second frame 46 b, which can be longitudinally spaced from the first frame 46 a, for example, by at least two of the spacers 44. Each of the spacers 44 can be attached to each one of the first frame 46 a and the second frame 46 b, for example, with a respective one of a plurality of fasteners 48, which can be rivets, as shown in FIG. 4.

Each of the first frame 46 a and the second frame 46 b, of each one of the first clamp jaw 22 and the second clamp jaw 24 of the first clamp member 16, and each one of the first clamp jaw 26 and the second clamp jaw 28 of the second clamp member 18, can be constructed from a plurality of layered plates 50, or from a single plate or bar. Three plates 50 can be used for each of the first frame 46 a and the second frame 46 b, as shown in FIG. 7. In other embodiments, one or both of the first frame 46 a and the second frame 46 b, of each of the first clamp jaw 22 and the second clamp jaw 24 of the first clamp member 16, and the first clamp jaw 26 and the second clamp jaw 28 of the second clamp member 18, can be constructed of other numbers of layered plates. The use of layered plates can result in ease of manufacturing and the associated cost reduction. The plates 50 of the first frame 46 a can be aligned with one another, and with each of the plates 50 of the second frame 46 b, for each of the first clamp jaw 22, the first clamp jaw 26, the second clamp jaw 24, and the second clamp jaw 28, which facilitates the use of apparatus 10 with straight sections of pipe, for example the first section of pipe 12 or the second section of pipe 14 shown in FIG. 1.

Each plate 50 of each of the first frame 46 a and the second frame 46 b, for each of the first clamp jaw 22 and the second clamp jaw 24 of the first clamp member 16, and each of the first clamp jaw 26 and the second clamp jaw 28 of the second clamp member 18, can define a plurality of apertures, which can be circumferentially spaced. In one embodiment, as shown in FIG. 9 with respect to one of the plates 50 of one of the frames 46 b, each plate 50 can define a plurality of apertures 52, which can be shaped to receive a fastener such as a rivet. In one embodiment, each of the apertures 52 can have a round shape. Each of the spacers 44 can be aligned with one of the apertures 52 in a respective one of the first frame 46 a and the second frame 46 b, to permit a fastener to pass through the first frame 46 a, the spacer 44, and the second frame 46 b, to attach the spacer 44 to each of the respective ones of the first frame 46 a and the second frame 46 b.

The first frame 46 a of each one of the first clamp jaw 22 and the second clamp jaw 24 of the first clamp member 16, and the first clamp jaw 26 and the second clamp jaw 28 of the second clamp member 18, can include a first end 54 a, a second end 55 a circumferentially spaced from the first end 54 a, and an inside surface 56 a having a radius 57 a (e.g., as shown in FIG. 3). The first frame 46 a can extend arcuately from the first end 54 a to the second end 55 a. The radius 57 a of the inside surface 56 a can be at least substantially the same, i.e., the same or substantially the same, as the radius of the outside surface of the portion of the section of pipe that the first frame 46 a surrounds. The second end 55 a of the first frame 46 a can include a radially outwardly extending portion 58 a and an ear 59 a extending transversely away from the radially outwardly extending portion 58 a.

Referring to FIG. 9, the second frame 46 b of each one of the first clamp jaw 22 and the second clamp jaw 24 of the first clamp member 16, and the first clamp jaw 26 and the second clamp jaw 28 of the second clamp member 18, can include a first end 54 b, a second end 55 b circumferentially spaced from the first end 54 b, and an inside surface 56 b having a radius 57 b. The second frame 46 b can extend arcuately from the first end 54 b, to the second end 55 b. The radius 57 b of the inside surface 56 b can be at least substantially the same, i.e., the same or substantially the same, as the radius of the outside surface of the portion of the section of pipe that the second frame 46 b surrounds. The second end 55 b of the second frame 46 b can include a radially outwardly extending portion 58 b and an ear 59 b extending transversely away from the radially outwardly extending portion 58 b. The configurations of the radially outwardly extending portions 58 a and 58 b, and the ears 59 a and 59 b, can facilitate clamping the first clamp member 16 to the second clamp member 18.

Referring to FIGS. 3, 5 and 20, each of the hinges 20 can include an arcuate portion 64 and a flange portion 65 extending away from the arcuate portion 64. The flange portion 65 can have a generally triangular shape, which can define an aperture 66 that can be shaped and sized to receive a flexible member, for example, a cable, which can be used as a “tie-off”, to prevent the apparatus 10 from inadvertently falling during assembly of the apparatus 10 to two adjacent sections of pipe. In other embodiments, the flange portion 65 can have any one of a variety of other shapes. In still other embodiments, the flange portion 65 can be omitted, for example, the hinge 20 shown in FIG. 2. Each of the hinges 20 can include an edge surface 67 (FIG. 20). At least an inside portion 68 of the edge surface 67 can be arcuate, and can be sized so that the hinges 20 do not contact the arcuate outside surfaces of the respective sections of pipe as the clamp members 16 and 18 pivot around the respective sections of pipe, for example the first section of pipe 12 and the second section of pipe 14 shown in FIG. 1. Accordingly, the clamp members 16 and 18 can pivot freely around the first section of pipe 12 and the second section of pipe 14. Each of the hinges 20 can be constructed from multiple layers of plates 21 made from a metal alloy or metal, which can enhance the ease of manufacturing and can reduce cost. Alternatively, each hinge 20 can be constructed as a unitary structure.

The arcuate portion 64 of one of the hinges 20 can be pivotally coupled with each of the first frame 46 a and the second frame 46 b of the first clamp jaw 22 of the first clamp member 16, and with each of the first frame 46 a and the second frame 46 b of the first clamp jaw 26 of the second clamp member 18. For example, one end of the arcuate portion 64 of the hinge 20 can be positioned within a space defined by the first frame 46 a and the second frame 46 b of the first clamp jaw 22 of the first clamp member 16, and pivotally coupled with each one of the first end 54 a of the frame 46 a, and the first end 54 b of the frame 46 b, of the first clamp jaw 22, using any suitable pivot member, e.g., rivets or clevis pins. The opposite end of the arcuate portion 64 of the hinge 20 can be similarly, pivotally coupled with each one of the first end 54 a of the frame 46 a, and the first end 54 b of the frame 46 b, of the first clamp jaw 26 of the second clamp member 18. The second hinge 20 can be similarly pivotally coupled with the second clamp jaw 24 of the first clamp member 16 and the second clamp jaw 28 of the second clamp member 18.

When the first clamp member 16 and the second clamp member 18 are positioned around respective portions of a first section of pipe and a second section of pipe, and each is in the closed position, the first clamp member 16 and the second clamp member 18 can be secured to one another. In one embodiment, the first clamp member 16 and the second clamp member 18 can be clamped to one another.

Apparatus 10 can include a pair of latch bolts 70 (FIGS. 4 and 7), which can be eye-bolts. One of the latch bolts 70 can be pivotally coupled with one of the first clamp jaw 26 of the second clamp member 18 (FIG. 4), and clamped to the first clamp jaw 22 of the first clamp member 16 (FIG. 4). The other latch bolt 70 can be pivotally coupled with the second clamp jaw 28 of the second clamp member 18 (FIG. 4), and clamped to the second clamp jaw 24 of the first clamp member 16 (FIG. 4).

As an example of the pivotal coupling of the latch bolts 70, the latch bolt 70 pivotally coupled with the second clamp jaw 28 of the second clamp member 18 can be pivotally coupled with the second end 55 a of the first frame 46 a, and the second end 55 b of the second frame 46 b, of the second clamp jaw 28, as shown in FIG. 2. This can be accomplished with a pivot member 71, which can be a pin. The pivot member 71 can be inserted through an aperture defined by the second end 55 a of the first frame 46 a, through an aperture defined by the latch bolt 70, and through an aperture defined by the second end 55 b of the second frame 46 b.

Apparatus 10 can include two latch plates 72, and one of the latch plates 72 can be retained on each of the latch bolts 70 by a latch bolt nut 73. In one embodiment, the latch bolt 70 pivotally coupled with the second clamp jaw 28 of the second clamp member 18 can be rotated to position the respective latch plate 72 against the outwardly extending portion 58 a of the second end 55 a of the first frame 46 a, and against the outwardly extending portion 58 b of the second end 55 b of the second frame 46 b, of the second clamp jaw 24 of the first clamp member 16. The nut 73 can then be tightened to clamp the second clamp jaw 24 of the first clamp member 16 to the second clamp jaw 28 of the second clamp member 18. The shape and size of the latch plate 72 can distribute the clamp load, or force, across the layered plates 50 of the first frame 46 a and the second frame 46 b of the second clamp jaw 24 of the first clamp member 16. The latch plate 72 can also provide a wear surface for the nut 73. The ear 59 a of the second end 55 a of the first frame 46 a, and the ear 59 b of the second end 55 b of the second frame 46 b, of the second clamp jaw 24, can facilitate retaining the latch plate 72 as the nut 73 is tightened. The latch bolt 70 pivotally coupled with the first clamp jaw 26 can be clamped to the first clamp jaw 22 in a similar manner. Alternatively, one of the latch bolts 70 can be pivotally coupled with the first clamp jaw 22 and clamped to the first clamp jaw 26, as shown in FIG. 19. Also, the other latch bolt 70 can alternatively be pivotally coupled with second clamp jaw 24 and clamped to the second clamp jaw 28.

Apparatus 10 can include a plurality of turnbuckle lugs 80 (FIGS. 13-15). Each of the turnbuckle lugs 80 can include a first portion 81 and a second portion 82 that can be integral with, and extend away from, the first portion 81. In one embodiment, the first portion 81 and the second portion 82 can be made as a unitary structure. The second portion of 82 of each of the turnbuckle lugs 80 can be generally T-shaped, and can include a rectangular insert 83 and a pair of posts 84, which can be integral with the insert 83 and can extend away from opposite sides of the insert 83. In one embodiment, each of the posts 84 can have a rectangular cross-sectional shape. Each one of the first clevis 40 and the second clevis 42 can define a slot that can be configured to receive the first portion 81 of a respective one of the lugs 80.

Referring to FIGS. 2 and 4, each one of a first plurality of the turnbuckle lugs, designated 80 a, can couple a respective one of the first plurality of turnbuckle assemblies 30 a with the first clamp jaw 22 of the first clamp member 16. In one embodiment, the first portion 81 of each one of the first plurality of turnbuckle lugs 80 a can be pivotally coupled with the first clevis 40 of a respective one of the first plurality of turnbuckle assemblies 30 a, and the second portion 82 of each one of the first plurality of turnbuckle lugs 80 a can be fixed to the first clamp jaw 22 of the first clamp member 16.

Each one of a second plurality of the turnbuckle lugs, designated 80 b, can couple a respective one of the first plurality of turnbuckle assemblies 30 a with the second clamp jaw 24 of the first clamp member 16. In one embodiment, the first portion 81 of each one of the second plurality of turnbuckle lugs 80 b can be pivotally coupled with the second clevis 42 of the first plurality of turnbuckle assemblies 30 a, and the second portion 82 of each one of the second plurality of turnbuckle lugs 80 b can be fixed to the second clamp jaw 24 of the first clamp member 16.

Each one of a third plurality of the turnbuckle lugs, designated 80 c, can couple a respective one of the second plurality of turnbuckle assemblies 30 b with the first clamp jaw 26 of the second clamp member 18. In one embodiment, the first portion 81 of each one of the third plurality of turnbuckle lugs 80 c can be pivotally coupled with the first clevis 40 of a respective one of the second plurality of turnbuckle assemblies 30 b, and the second portion 82 of each one of the third plurality of turnbuckle lugs 80 c can be fixed to the first clamp jaw 26 of the second clamp member 18.

Each one of a fourth plurality of the turnbuckle lugs, designated 80 d, can couple a respective one of the second plurality of turnbuckle assemblies 30 b with the second clamp jaw 28 of the second clamp member 18. In one embodiment, the first portion 81 of each one of the fourth plurality of turnbuckle lugs 80 d can be pivotally coupled with the second clevis 42 of a respective one of the second plurality of turnbuckle assemblies 30 b, and the second portion 82 of each one of the fourth plurality of turnbuckle lugs 80 d can be fixed to the second clamp jaw 28 of the second clamp member 18.

For each one of the first plurality of turnbuckle lugs 80 a, the second plurality of turnbuckle lugs 80 b, the third plurality of turnbuckle lugs 80 c, and the fourth plurality of turnbuckle lugs 80 d, one of the posts 84 can be positioned within an aperture defined by the first frame 46 a of the respective clamp jaw, for example the first clamp jaw 22 of the first clamp member 16, and the other post 84 can be positioned within an aperture defined by the second frame 46 b of the respective clamp jaw, for example, the first clamp jaw 22 of the first clamp member 16.

Each one of the first plurality of lugs 80 a, the second plurality of lugs 80 b, the third plurality of lugs 80 c, and the fourth plurality of lugs 80 d, can be pivotally coupled with the respective one of the first plurality of turnbuckle assemblies 30 a and the second plurality of turnbuckle assemblies 30 b, using clevis pins, or by any other suitable pivot structure. Clevis pins can enhance the speed and ease of assembly by a work crew.

Referring to FIGS. 1-8, apparatus 10 can include a plurality of threaded members 86, which can be bolts, which can be used to provide further adjustment, or fine turning, of the alignment of two sections of pipe, for example the first section of pipe 12 and the second section of pipe 14 shown in FIG. 1. Each of the threaded members 86 can be threaded through an aperture 87 defined by a respective one of the first clevis 40 and the second clevis 42 of a respective one of the turnbuckle assemblies 30, at a location that can be longitudinally spaced from a threaded bore 45 in the first clevis 40, and from a threaded bore 47 in the second clevis 42, which receive the rod 32.

For example, for each of the first plurality of turnbuckle assemblies 30 a, a threaded member 86 can be threaded into and through the aperture 87 defined by the first clevis 40 and into contact with the first portion 81 of a respective one of the first plurality of turnbuckle lugs 80 a. Another threaded member 86 can be threaded into and through the aperture 87 defined by the second clevis 42, and into contact with the first portion 81 of a respective one of the second plurality of turnbuckle lugs 80 b. Further rotation of the threaded members 86 can cause the turnbuckle lugs 80 a and 80 b to force the respective one of the first clamp jaw 22 and the second clamp jaw 24 to pivot inwardly. This can cause the respective sections of pipe to move laterally, to provide further adjustment to the alignment of two sections of pipe, for example, the first section of pipe 12 and the second section of pipe 14.

Selective operation of all of the threaded members 86 can result in a fine tuning of the lateral alignment of two sections of pipe. Also, selective operation of the threaded members 86 can vary the orientations of the opposing end faces of the two sections of pipe, between an angular orientation and a parallel orientation within certain limitations, for example the limitations of movement of the turnbuckle assembles 30, and within limits determined by the requirements of the particular installation.

The adjustment of the lateral positions of the sections of pipe with the threaded members 86 can result in significant forces being applied to the respective ones of the turnbuckle assemblies 30. However, the turnbuckle assemblies 30 can be sized and configured to minimize the resultant stresses. For example, the threaded members 86 can extend transversely through a solid portion 41, 43 of the respective clevis 40, 42, of the respective turnbuckle assembly 30. Each of the solid portions 41 and 43 can have a significantly larger cross-sectional area than the rods 32 of the turnbuckle assemblies 30. The smallest cross-sectional area of each turnbuckle assembly 30 can be the cross-sectional area of each of the exposed portions of the rod 32, i.e., the portions of the rod 32 positioned between the torquing member 34 and the first clevis 40, and between the torquing member 34 and the second clevis 42. Clevis 40 has a length L1 and clevis 42 has a length L2 (FIG. 11). The length L1 of the clevis 40 and the length L2 of the clevis 42 can be sized so that the interfaces between the torquing member 34 and the exposed portions of the rod 32, as well as the interfaces between each of the clevises 40, 42 and the exposed portions of the rod 32, can be sufficiently spaced longitudinally from the threaded members 86.

In one embodiment, for each one of the first plurality of turnbuckle assemblies 30 a and each one of the second plurality of turnbuckle assemblies 30 b, the torquing member 34 can include a first end surface 88 and a second end surface 89 spaced from the first end surface 88 by a first distance D1 (FIG. 11). The first end surface 88 can be spaced from the first clevis 40 by a second distance D2 (FIG. 10) and the second end surface 89 can be spaced from the second clevis 42 by a third distance D3 (FIG. 10). The length L1 of the first clevis 40 and the length L2 of the second clevis 42 can each be greater than each one of the first distance D1, the second distance D2, and the third distance D3. Additionally, the torquing member 34 can be positioned at least substantially midway, i.e., midway or substantially midway, between the first clevis 40 and the second clevis 42.

FIGS. 22-25 illustrate an apparatus 110 for aligning sections of pipe according to another embodiment. FIG. 22 illustrates the apparatus 110 in association with a straight section of pipe 112 and an L-shaped section of pipe 114. The apparatus 110 can include a first clamp member 116 and a second clamp member 118, which can be clamped together when the first clamp member 116 and the second clamp member 118 are in their respective closed positions, in surrounding and contacting relationship with respective portions of the first section of pipe 112 and the second section of pipe 114.

The first clamp member 116 can include a first clamp jaw 122 and a second clamp jaw 124 longitudinally spaced from the first clamp jaw 122. The second clamp member 118 can include a first clamp jaw 126 and a second clamp jaw 128 longitudinally spaced from the first clamp jaw 126. Apparatus 110 can include a first plurality of turnbuckle assemblies 130 a, which can be coupled with each one of the first clamp jaw 122 and the second clamp jaw 124 of the first clamp member 116. Apparatus 110 can also include a second plurality of turnbuckle assemblies 130 b, which can be coupled with each one of the first clamp jaw 126 and the second clamp jaw 128 of the second clamp member 118. Each of the first clamp jaw 122 and the second clamp jaw 124 of the first clamp member 116, and each of the first clamp jaw 126 and the second clamp jaw 128 of the second clamp member 118, can include a first frame 146 a and a second frame 146 b longitudinally spaced from the first frame 146 a. Each of the frames 146 a and 146 b can include a plurality of layered plates 150. Each of the frames 146 a can extend arcuately from a first end 154 a to a second end 155 a, and each of the second frames 146 b can extend arcuately from a first end 154 b to a second end 155 b.

The plates 150 of the frames 146 a and 146 b of one or more of the first clamp jaw 122 of the first clamp member 116, the second clamp jaw 124 of the first clamp member 116, the first clamp jaw 126 of the second clamp member 118, and the second clamp jaw 128 of the second clamp member 118, can be configured to accommodate the shape of the L-shaped section of pipe 114. For example, in one embodiment, the plates 150 of each of the frames 146 a and 146 b of the first clamp jaw 122 of the first clamp member 116, and the plates 150 of each of the frames 146 a and 146 b of the first clamp jaw 126 of the second clamp member 118, can be offset relative to one another, as shown in FIGS. 24 and 25. Referring to FIGS. 23-25, each of the plates 150 of the first frame 146 a of the first clamp jaw 122, and each of the plates 150 of the first frame 146 a of the first clamp jaw 126, can taper, or reduce in width, from the second end 155 a to the first end 154 a, by varying amounts. Similarly, each of the plates 150 of the second frame 146 b of the first clamp jaw 122, and each of the plates 150 of the second frame 146 b of the first clamp jaw 126, can taper, or reduce in width, from the second end 155 b to the first end 154 b, by varying amounts.

Apparatus 110 can include two hinges 120, which can hingedly couple the first clamp member 116 with the second clamp member 118. The two hinges 120 can have different colors, for ease of identification of the apparatus 110, which can facilitate a worker in selecting the desired apparatus for a particular application. The components and configuration of the apparatus 110 can otherwise be the same as, or similar to, the components and configuration of apparatus 10.

FIGS. 26-29 illustrate a shoe insert 90 according to one embodiment. An assembly can be made from a kit of components that can include a plurality of the shoe inserts 90, of a variety of sizes. In one embodiment, the assembly can include the apparatus 10 and two pairs of the shoe inserts 90 coupled with the apparatus 10, to adapt apparatus 10 for use with two adjacent sections of pipe, which each have a smaller outside diameter than the outside diameter of pipes that the frames 46 a and 46 b of apparatus 10 are sized to engage.

Each shoe insert 90 can include an arcuate portion 91 and a flange portion 92, which can be attached to the arcuate portion 91. The arcuate portion 91 can include a plurality of arcuate plates 93, which can be attached to one another with one or more conventional fasteners 75, for example, rivets or mating bolts and nuts. Each of the arcuate plates 93 can include an inside surface 94 that has a radius 95. The radius 95 can be smaller than a radius 57 a of an inside surface 56 a of each of the frames 46 a of apparatus 10, and can be smaller than a radius 57 b of an inside surface 56 b of each of the frames 46 b of the apparatus 10.

The flange portion 92 can include a plurality of flange plates 96, which can be spaced as shown in FIG. 27. The flange plates 96 can be attached to each other, and to the arcuate plates 93, using one or more of the conventional fasteners 75. Each flange plate 96 can include a pair of shoulders 97, and can define an aperture 98 (FIG. 26). Each shoe insert 90 can be coupled with the apparatus 10 by aligning the aperture 98 with apertures defined by respective ones of the frames 46 a and 46 b, and inserting any suitable fastener, e.g., a pin or bolt, which can be secured, e.g., with a clip or nut, respectively, so that the fastener can be removed easily. When each of the shoe inserts 90 is coupled with apparatus 10, each of the shoulders 97 of each shoe insert 90 can cooperate with a respective one of the turnbuckle lugs 80, for example, the second portion 82 of the respective one of the turnbuckle lugs 80, to at least inhibit, i.e., prevent or inhibit, rotation of the shoe insert 90.

The apparatus for aligning sections of pipe (e.g., 10, 110) can be used to quickly and accurately position the ends of adjacent sections of pipe in optimum relation for welding, or otherwise joining, the sections of pipe to form a continuous pipe. Accordingly, the apparatus (e.g., 10, 110) can facilitate the rapid construction of pipelines for the conveyance of gases or liquids. One application of the apparatus (e.g., 10, 110) is to align adjacent sections of pipe that may be imperfect due to minor variances in the outside diameter of one or both of the pipe sections to be joined.

Apparatus 10 can be advantageously used to align two straight sections of pipe, while apparatus 110 can be advantageously used to align a straight section of pipe with an L-shaped section of pipe. In other embodiments, apparatus according to the inventive principles can be advantageously used to align other combinations of straight, L-shaped, and T-shaped sections of pipe.

The apparatus (e.g., 10, 110) can be used to adjust the relative positions of adjacent sections of pipe both longitudinally and laterally, or transversely. Also, within certain limitations, the apparatus (e.g., 10, 110) can be used to vary the orientations of the opposing end faces of the two adjacent sections of pipe, between an angular orientation and a parallel orientation. These and other advantages will be described with regard to apparatus 10 for purposes of illustration and not of limitation.

The first clamp member 16 and the second clamp member 18, can be hingedly coupled, with each being pivotally coupled with a pair of hinges (e.g., 20), which facilitates positioning apparatus 10 in surrounding relationship with the two sections of pipe to be joined. Once apparatus 10 is in position, the first clamp member 16 can be clamped to the second clamp member 18 so that each of the clamp members 16, 18 engages each section of pipe to be joined. This can securely hold the two sections of pipe during the welding process, which can enhance the accuracy of the weld.

The relative longitudinal positions of two adjacent sections of pipe can be accurately and easily adjusted using turnbuckle assemblies (e.g., 30). Each of the first clamp jaw 22 of the first clamp member 16 and the first clamp jaw 26 of the second clamp member 18, can partially surround, and be forced against, respective portions of a first section of pipe. Each of the second clamp jaw 24 of the first clamp member 16 and the second clamp jaw 28 of the second clamp member 18, can partially surround, and be forced against, respective portions of a second section of pipe. A first plurality of the turnbuckle assemblies 30 (e.g., 30 a) can be coupled with each one of, and can vary the longitudinal spacing between, the first clamp jaw 22 and the second clamp jaw 24 of the first clamp member 16. Similarly, a second plurality of the turnbuckle assemblies 30 (e.g., 30 b) can be coupled with each one of, and can vary the longitudinal spacing between, the first clamp jaw 26 and the second clamp jaw 28 of the second clamp member 18. Accordingly, the first plurality of turnbuckle assemblies 30 a and the second plurality of turnbuckle assemblies 30 b can be adjusted, by rotating the respective torquing member 34 and rod 32, to accurately and easily adjust the longitudinal positions of the first and second sections of pipe.

The configuration of apparatus 10 can provide unobstructed access to the weld joint, which can enhance the accuracy and speed of the welding process. The unobstructed access results from the longitudinal spacing of the first clamp jaw 22 and the second clamp jaw 24 of the first clamp member 16, the longitudinal spacing of the first clamp jaw 26 and the second clamp jaw 28 of the second clamp member 18, the circumferential spacing of the first plurality of turnbuckle assemblies 30 a along the first clamp member 16, and the circumferential spacing of the second plurality of turnbuckle assemblies 30 b along the second clamp member 18.

The devises of the turnbuckle assemblies (e.g., 40, 42) can be color coded to facilitate coordinated adjustment of the turnbuckle assemblies by a work crew. For example, devises having a first color can be threaded onto a first portion of the respective rod 32 of the turnbuckle assembly 30, which has right-hand threads, and devises having a second, different color can be threaded onto a second portion of the rod 32, which has left-hand threads. In this manner, rotation of the rods 32 of each turnbuckle assembly 30 in a first direction can cause the first clamp jaw 22 to move away from the second clamp jaw 24, and can cause the first clamp jaw 26 to move away from the second clamp jaw 28, while rotation of the rod 32 of each turnbuckle assembly 30 in an opposite direction can cause the respective clamp jaws to move toward each other.

The relative lateral positions of two adjacent sections of pipe can be accurately and easily adjusted by selective operation of the threaded members 86 of apparatus 10, which can be bolts that may be referred to as “jack bolts”. Each of the threaded members 86 can be threaded through one of the clevises (e.g., 40, 42) of the respective turnbuckle assembly 30 and into contacting engagement with one of the lugs 80 of apparatus 10, with further rotation of the threaded member 86 causing one of the clamp jaws of apparatus 10 to pivot inwardly, which in turn can cause one of the sections of pipe to move laterally. For example, rotation of the threaded members 86 that extend laterally, or transversely, through the clevis 40 of a corresponding one of the first plurality of turnbuckle assemblies 30 a, and into engagement with a respective one of the turnbuckle lugs 80 a, can cause the first clamp jaw 22 of the first clamp member 16 to pivot inwardly, which can cause lateral movement of the respective section of pipe.

As may be appreciated, use of the threaded members 86 to adjust the lateral positions of sections of pipe, can result in significant forces being applied to the respective turnbuckle assemblies 30. However, the turnbuckle assemblies 30 can be configured to minimize the resultant stress. For example, the threaded members 86 can extend transversely through a solid portion (e.g., 41, 43) of the clevis (e.g. 40, 42) of the respective turnbuckle assembly 30, which can have a significantly larger cross-sectional area than the rod 32 of the turnbuckle assembly 30. Also, the lengths of the devises (e.g., 40, 42) can be sized so that the interfaces between the torquing member 34 and the exposed portions of the rod 32, i.e., outside of the devises, as well as the interfaces between each of the clevises 40, 42 and the exposed portions of the rod 32, are sufficiently spaced longitudinally from the threaded members 86.

Each of the frames (e.g., 46 a, 46 b) of each of the clamp jaws (e.g., 22, 24) of the first clamp member 16, and each of the frames (e.g., 46 a, 46 b) of each of the clamp jaws (e.g., 26, 28) of the second clamp member 18, can be constructed from a plurality of plates 50, for example three plates 50 in one embodiment, which can enhance the ease of manufacturing and reduce cost. Similarly, each of the hinges 20 can be constructed from multiple plates, for example, two or more plates, which can also enhance the ease of manufacturing and reduce cost.

Piping is generally available in standard sizing throughout the industry. Accordingly, the apparatus for aligning sections of pipe (e.g., 10, 110) can be constructed to accommodate standard piping sizes. However, a pair of shoe inserts (e.g., 90) can be coupled with the apparatus (e.g., 10, 110) to adapt the apparatus (e.g., 10, 110) for use with a pipe having a smaller outside diameter. For example, the inside radius of each of the shoe inserts 90 can be smaller than the inside radius of the frames (e.g., 46 a, 46 b) of the first and second clamp jaws (e.g., 22, 24; and 26, 28) of the first and second clamp members (e.g., 16, 18) of the apparatus 10. The use of shoe inserts 90 to adapt the apparatus 10 for use with a smaller size pipe, can enable greater economy because a complete separate apparatus may no longer be needed for every size of pipe encountered. For example, a properly sized shoe insert 90 would allow the combination of the apparatus 10 and a pair of the shoe inserts 90 to be used with a pipe having a four inch outside diameter, instead of a pipe having a six inch outside diameter, without the need or use of another tool. A kit of parts including the apparatus (e.g., 10, 110) and shoe inserts (e.g., 90) having a variety of inside radiuses, can permit the use of the apparatus (e.g., 10, 110) with multiple pipes having different outside diameters.

While various embodiments of an apparatus for aligning sections of pipe, and an assembly made from a kit of components, have been described in considerable detail, it is not intended to restrict or in any way limit the scope of the appended claims to such detail. Additional modifications will be readily apparent to those skilled in the art.
